Abstract

A pair of electrodes (1a, 1b) are formed on one surface of a dielectric substrate (2) . A dielectric layer (18) is formed on the surface of the dielectric substrate (2) so as to cover the pair of electrodes (1a, 1b). The pair of electrodes (1a, 1b) have linear electrode elements, respectively. The respective linear electrode elements are arrange at equal intervals.
